Abstract
Embodiments of a data representation system for describing specific data sets, such as documents, web pages, or search engine queries, based on data tokens, such as words or n-grams, contained in a collection of documents are described. Such a system can be used in any type of information retrieval application, such as a document, web page, or online advertisement serving process, based on an information request, such as a query executed through an Internet search engine. For example, when a search is performed at a search engine, a content provider uses the system to represent the search query and compares the query representation against representations of a set of content in order to identify, retrieve and aggregate the content from the set most relevant to the search query, in the form of a web page or other data unit for display or access through the web browser.
